How often do allergists hear: “I am allergic to fish and therefore I am allergic to the iodine in radiocontrast dye”?
The long-standing misconception that there is a higher incidence of allergic reactions to radiocontrast media (IVP dye) in those with seafood allergy is alive and well. And, this misunderstanding is pervasive among both physicians and patients.
In a survey of 231 faculty radiologist and interventional cardiologists at 6 midwest academic medical centers, sixty-nine percent of responders indicated that they inquire about a history of seafood allergy before radiocontrast media administration. Some 37.2% of responders replied that they would withhold radiocontrast media or recommend premedication on the basis of a history of seafood allergy.
Medical research has proven time and time again that there is no cross-reactivity between these substances. Physician education with respect to seafood allergy and radiocontrast media administration is vital to halting the persistence of this misconception.
